Great Quality & Excellent Service You can trust!

Our latest model OPTI6800SDE 6500 watt Silent Diesel Generator has much improvement, e.g.,using glass fiber cover for wiring, removing capacitor from alternator for better ventilation & easy maintenance and using a metal sheet for protecting wiring and harness from overheating. Our on-site testing shows that the temperature rise in muffler side cover was only 50~60 degree C after the generator ran 5 hours. The generator will labor ideally and better than you have ever expected! We are the only maker and supplier of this improved model for sale in North America Market. 110V~240V for both 60HZ and 50 HZ version available. If interested in 50 Hz unit, please contact us for detailed information.
